SIDE BEARING FOR CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 582,343, dated May 11,1897.

7 Application filed March 6, 1897. Serial No. 626,282. (No model.)

' and I do declare the following to be a f ull,clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference markedthereon, which form tion. I

The invention relates to side bearings for car-trucks; and it consistsin the novel features hereinafter described and claimed and by whichimportant advantages are secured.

The side bearing embodying my present invention comprises a base-platecontaining a depression to receive the spring or springs, an exposedcasing secured to said base-plate and encompassing said depression, andan upper exposed yielding shell or casing covering the spring or springsand adapted to receive the impact of the car-body, all as hereinaftermore fully described, and illustrated in the accompanying drawings, inwhich- Figure 1 is a top view of a portion of a cartruck provided with aside bearing constructed in accordance with and embodying theinvention;and Fig. 2 is a central vertical section, through the side bearing andthrough a portion of the car-truck, on the dotted line 2 2 of Fig. 1.

In the drawings, A A designate a portion of the transom-beams of acar-truck, and B the usual top plate connecting said beams and beingeither in a separate piece or integral withtheusualsideframe. (Notshown)The top plate B has heretofore received side bearings, but has notheretofore been utilized to form a section of the side-bearing casing,and in the present instance the top plate B forms the base-plate for theside bearing and contains the depression 0, which, as shown in Fig. 2,extends below the horizontal upper surface of the top plate and of thetransombeams.

The depression 0 is confined to that portion of the top plate directlyin vertical alinement a part of this specificawith the remaining partsof the side bearing and the depressed portion 0 inoutline is conformedto the outline of the upper parts of the side bearing and to thesprings.

Upon the top plate B, directly in alinement with the depression Ctherein, is securely riveted or bolted the casing D, which comprises thehorizontal flange E, contacting with the upper surface of the said topplate, and the vertical inwardly-inclined flange F, within which isarranged the yielding casing G, which incloses the upper portion of thesprings H and is adapted to have a vertical movement within the rim orcasing D under the pressure of the car-body.

The sides of the casing G are slightly inclined, so as to pass freelydownward within the casing D, and at its opposite ends the casing G isprovided with the projecting ends or hollow lugs I, which are within theend recesses or guides J, formed in the casing D. The lugs I andrecesses J cooperate with one another to guide the casing G in itsmovement and to prevent the casing G from escaping from position withinthe casing D. The springs H have-their lower ends resting upon the uppersurface of the depression 0, and their upper ends receive and supportthe yielding casing G. In the present instance the ends of the casings Dand G are in general contour circular, and at their opposite sides thecasings D G are curved inward, as shown in Fig. 1, thus conforming aslargely as practicable to the circular outlines of the springs whenviewed in horizontal section.

The depression 0 in its end and side outlines. corresponds with the formof the casing G, and, as illustrated more clearly in Fig. 2, the lengthand width of the depression 0 are less than the length and width of thecasing D, but substantially correspond with the length and width of thecasing G, which more closely encompasses the springs H than does thecasing D. Thus the depression 0 and casing G asclosely as practicableconfine the springs H at their lower and upper ends, respectively, andthereby the said springs are perfectly controlled as to their position.

A further advantage of the depression '0 is that by means thereof and bycausing the same to form a lower section to the side-bearing casing I amenabled to use sufiiciently long springs H to properly relieve thecarbody during its lurching and jarring.

The side bearing embodied in the present application comprises the topplate having the depression 0, constituting the lower section of theside-bearing casing, the stationary casin g D, secured upon said topplate, and the yielding casing G, confining the springs and being inalinement with the said depression 0. If the top plate Bis of wroughtmetal, the depression 0 may be pressed therein, and if the top plate isof cast metal the depression 0 may be cast therein. The invention isnot, however, limited to any special means or method of producing thedepression 0 in the top plate B; nor is the invention limited in everyinstance to the employment of the two springs H II with the specialoutline of casingsD G illustrated in the drawings, although in itsnarrower form said invention is limited to the employment of the severalsprings H H and to the special outline of easing shown in connectionwith the special outline of depression O illustrated. The depression 0will usually be provided with openings K for the purpose of permittingthe escape of dust from within the casing of the side bearing.

The side bearing constructed as above described is entirely durable andeificient and fully capable of resisting in a proper manner the car-bodyduring its lurching and other movements when in actual service.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The side bearing comprising the base having -the depression toreceive the lower end of the spring or springs, the casing secured tosaid base and having the upwardlyextending rim encompassing saiddepression, and the yielding casing guided within said rim and inclosingthe upper portion of the said spring or springs; substantially as setforth.

' 2. The side bearing comprising the base having the depression toreceive the lower end of the spring or springs, the casing secured tosaid base and having the upwardlyextending rim encompassing saiddepression, and the yielding casing guided within said rim and inclosingthe upper portion of the said spring or springs, said rim being greaterin diameter than said depression and said yielding casing being ofsubstantially the same diameter as said depression; substantially as setforth.

3. The side bearing comprising the base B having the depression 0 toreceive the spring or springs, the casing D having the horizontal flangeE secured to said base and the upwardly-extending rim F, and theyielding casing G guided within said rim and resting on said spring orsprings; substantially as set forth.

4. The side bearing comprising the base 13 having the depression 0 toreceive the spring or springs, the casing D having the horizontal flangeE secured to said base and the upwardly-extending rim F provided withthe end recesses J, and the yielding casing G guided Within the said rimand having the end lugs I within said recesses J; substantially as setforth.

5. The side bearing comprising the base B having the depression 0, theplurality of springs having their lower ends within said depression, thecasing D having the horizontal flange E secured to said base and theup-- \vardlyextending rim F, the yielding casing G guided within saidrim and resting on said springs, said depression and said yieldingcasing conforming along their sides to the outlines of said springs andmaintaining them in proper position; substantially as set forth. Intestimony whereof I affix my signature in presence of two witnesses.
